If you're a web developer and are considering getting more into mobile application development for IOS and/or Android operating systems for mobile phones, then you are likely go ask the question, "What Programming Language is Best for Mobile App Development?".

The answer is somewhat complicated because there are many answers. To narrow down the possible options, I am going to make a couple assumptions. I will assume that you, like myself, like to stay away from platforms and drag and drop type UI tools to program with. I will also assume that you want to develop something for both Android and iPhone, not just one or the other.

Considering the above assumptions, there are still many options, so what makes it such a complicated choice? In my opinion the main factor that makes it so difficult to pick a coding language to specialize in for mobile app development is the fact that there are two main and competing mobile platforms that have chosen to use different languages with their operating systems. Of course I am speaking about Android Vs. iOS.

Android Vs. iOS, Which is More Popular?

A quick Google search shows me that just over 85% of smartphones are Android, while most of the remaining 15% are Apple iOS phones. According to an article I read on 9to5mac.com, Android and iOS together account for 99.1% of all smartphones in use today, which makes any other devices almost pointless to develop for. It is worth mentioning that of the 0.9% of devices that are not running Android or iOS operating systems, are mostly running Windows operating systems. Windows OS accounts for 0.6%, while 0.1% are Blackberry and the remaining 0.2% are various other operating systems that are not popular enough to be worth even mentioning here.

Best Languages for Android OS

JAVA

Since Android controls the majority of the market for smartphones today, let's look at them first. If you are going with the most popular answer, than Android wins by far! Android operating systems use Java. If you are coding an app for Android phones, Java is most likely going to be your best programming language to choose as the base language for your app. In reality, many apps use a combination of several different languages. However, in my experience your language of choice will make up the majority of the app's code.

Kotlin

Kotlin, a second app development language option, was designed and developed by JetBrains. They are a Czech company known for the popular IDE, IntelliJ IDEA. Google's Android team recently announced that they are officially adding support for the Kotlin programming language. Kotlin was created to address some of the Java issues. Some say the Kotlin syntax is clean, simple, and leads to less code bloat.

Best Languages for iOS

While Apple's iOS operating system only accounts for roughly 15% of the smartphone market, that is still a significant number of devices out there. Smart developers create apps for both Android and iOS, whether it be with separate apps for each or some sort of platform used to create a mashup that will allow a single app to function on both operating systems.

Apple iOS apps primarily use SWIFT or Objective-C

SWIFT

SWIFT is a quickly growing open source language popular with many starting out with app development today. Apple has heavily promoted the use of SWIFT making it clear that they intend for SWIFT to be the leading language choice for iOS application developers.

Objective-C

Objective-C was the original language of the iOS operating system, but is being phased out apparently since Apple is making it clear that SWIFT is the future, then that leaves Objective-C stuck in the past. While it is still a viable option, I would suggest using it only on an as-needed basis for iOS application development purposes.

Cross -Platform Mobile App Language Options

For some of you, particularly those of you who don't want to make two separate apps, a cross-platform language option might seem more attractive. A cross-platform language in this context, is one that will allow a mobile application to function on both Android and iOS without the need to make two applications, one for each OS.

JavaScript

If you started out as a web developer as I did, then you are surely familiar with JavaScript. Not to be confused or associated with Java, JavaScript is it's own language despite the similar name. JavaScript is very versatile in that you can complete many different types of tasks using the language. It is probably one of the most popular cross-platform options because it is effective and rather light-weight.

Several JavaScript frameworks exist today that target the mobile application development market. While I am not a huge fan of most frameworks in general, some of these deserve some serious consideration none-the-less. Some of the well known JavaScript frameworks popular today include PhoneGap by Cordova, Angular.js, jQuery Mobile and React. There are many more that are worth researching if you are looking for a cross-platform JavaScript framework or library to help build your next mobile application for Android and iOS. Actually, JavaScript apps will also work on the other less used Operating Systems as well such as Windows OS and Blackberry.

Today, I'm writing a rather simple WordPress Ajax example that demonstrates how to user Ajax in a wp-admin page from a WordPress Plugin.

Using Ajax in wp-admin is a little easier than using it on the front-end of a WordPress site because of the ajaxurl JavaScript global variable which refers to the admin-ajax.php url.

In the following code example the goal is to provide an admin page with a delete post link that is powered by Ajax. Therefore the code enables the deletion of a WordPress post without the obtrusive page refresh!

This is a pretty bare-bones example meant as a learning tool. It could be fleshed out much more to be more practical, but I wanted to keep it simple to get the main point across, which is how to do a simple Ajax request from wp-admin.

The Essential Code

First, for those of you that only need to see the basics, I'll demonstrate the essential code for the Ajax to work. Further down this page, I'll put it all together in a simple plugin for those of you that may need to see a working example to grasp the concept better. Here is the essential code to enable an Ajax delete post button:

First, a simple HTML line to call our JavaScript function onclick:

In the above, you'll notice the ajax_delete_posts JavaScript function is called. ajax_delete_posts is the function we must create! Of course you'll need to define the post id in $ID and the post tile in $title using PHP, but this is just to show you how I intend to call the Ajax/JavaScript function

Second, we use PHP to generate our ajax_delete_posts function in JavaScript code:

You can rename the ajax_delete_posts as you wish, just make sure to rename it in your HTML above too if you do. Here's the code to generate the JavaScript from within your PHP file, the plugin's main file normally:

Notice in the above code how we pass the post id to the JavaScript function using the "t" variable. Also it's important to note your data variable's action value as you will need to use the same value for the function name in the below code. Feel free to use whatever text you want for the action as long as it can be an appropriate PHP function name in the code below as well.

Finally, the third step is to add your PHP function named after the action named above and also hook into it with "wp_ajax_" followed by the action named above as well, so in our case the hook we use would be "wp_ajax_del_posts_with_ajax". However, if you use a different action, such as "do_aj" for example, then your action hook would read "wp_ajax_do_aj". Got it? I hope so, but the code example should help too, so here it is:

In the above code example, we first set up our action hook by using the hook "wp_ajax_" followed by the action we used in the "var data" line further above. Then we write a PHP function named exactly like the action we used above and be sure to also name the function as the parameter in the action hook as well and you will be good to go!

Putting it all together in a simple Ajax WordPress Plugin

Next I'll show you the example plugin I created to demonstrate exactly how this all works together in case some of you failed to grasp it from my previous explanations. You can cut and paste the following PHP code into a file named "ajax_post_delete.php" and place it on your desktop in a folder named "ajax_post_delete" and I promise you the code will function on any standard WordPress installation as of the day I wrote this. Here is the complete "Ajax Post Delete" WordPress plugin code in a single file example plugin:

That's it! copy and paste the above code into your .php file and you've got a simple WordPress plugin that will demonstrate the use of Ajax effectively in a custom admin page of your WordPress website. Feel free to modify the code as needed, but please change the plugin name if you intend to distribute it. Thank you and Good Luck!

The EDD Instant Updater WordPress plugin is a plugin I created while working with a custom WordPress plugin that needed to have instant update notifications while using Easy Digital Downloads(EDD). EDD comes with it's own updater class, but it uses the default WP standards which means you have to wait up to 12 hours after you push an update to get the notice in the WordPress dashboard! With the EDD Instant Updater plugin, you no longer have to wait, the plugin update notices come to you instantly! No more delays!

My wonderful client wanted me to add a .CSV importer that imports posts into a Custom Post Type(CPT) in large quantities of around 10k to 50k at a time.

What a standard WordPress site can handle

From my experience building plugins and importers for WordPress over the past 20 years, I have learned to expect trouble if you try to import anything more than 4k to 5k posts into WP at a time. The main requirement for the importer that I am building now is that it is able to import 20k posts in under 15 minutes. Not too difficult, but a challenge none-the-less because the average WP site will timeout after the first 4k posts on average. I also wanted to accomplish this goal without using any bloated PHP Que libraries or Worker Libraries, so I'll be developing it completely from scratch, just like a grown up!

Step One, Break Large File into Smaller Chunks

The first thing I did while developing my large WP file import feature, was to handle the issue of having a huge .csv file with 20 thousand posts saved in it. What do you do? What I did was wrote a PHP script that reads in that huge file and breaks it up into manageable chunks and saves each chunk to its own separate .csv file. Kind of simple really, this is the easy part!

I created a file named file_split.php to handle this portion of the importer's code. Here are the contents of that file:

<?php
$chunk_size = 2000;//size of ea. chunk file given in the no. of lines written to the file(excluding the first line with headings that will be at the top of ea. chunk file created).
$max_files = 0;//it will stop after writing this many files, set to 0 for no limmit
$u = $uploadpath;//"double_accounts-test.csv";
//read a file line by line:
echo "<p>Opening $u to spit it into chunks......</p>";
$file = fopen($u, "r") or exit("Unable to open $u!");
//extract the first line from the file:
$first_line = fgets($file);
//Output a line of the file until the end is reached:
$i=0;
$ii=0;
$iii=0;
$chunk=$first_line;
while(!feof($file) &&($iii < $max_files||$max_files==0)) {
$i++;
$ii++;
$line = fgets($file);
//echo "$i) $line<br>";
//add line to lines that get written to files:
$chunk .= $line;
//once we get to chunk_size lines, write a new file
if($ii == $chunk_size){
$iii++;
//echo "<h3>Chunk #$iii:</h3>";
//echo $chunk;
//create dynamic filenames:
$fn = ABSPATH."wp-content/plugins/YOUR-PLUGIN/temp/chunk$iii.csv";
//echo "Writing file $fn....<br>";
$fh = fopen($fn, 'w') or die("can't open $fn file to overwrite");
fwrite($fh, $chunk);
fclose($fh);
$m = "<span style='color:green'>Chunk Written to $fn</span><br>";
//reset $ii var back to zero:
$ii = 0;
//empty the $chunk var and add first line to top of file content($chunk)
$chunk=$first_line;
//echo "<hr><span style='text-align:center;color:orange;font-weight:bold;width:100%;margin-right:111px'>End File #$iii</span>$m<hr>";
echo $m;
//add the file name to the fnames array:
$fnames[] = $fn;
}//end if $ii = $chunk_size
}
fclose($file);
//if $ii is greater than 0 and less then chunk_size, then there was a left over chunk at the end, so write it to a file too:
if($ii > 0 && $ii < $chunk_size){
$noof_files = $iii+1;
$fn = ABSPATH."wp-content/plugins/YOUR-PLUGIN/temp/chunk$noof_files.csv";
echo "Left over chunk of $ii lines remains, so writing it to final file named $fn....<br>";
//echo "Writing Final file $fn....<br>";
$fh = fopen($fn, 'w') or die("can't open $fn file to write final chunk!");
fwrite($fh, $chunk);
fclose($fh);
echo "<h3 style='color:green'>FINAL Chunk Written to $fn! DONE chunking $u file! Total files created: $noof_files</h3>";
//add final file name to fnames array:
$fnames[] = $fn;
}else{
echo "Wow! We broke even with no left over chunk of less than $chunk_size lines, so finished writing files! Final file is $fn.<br>";
}

?>

Put the file_split.php file up for now. We will include it in another file later when we have the rest of our import feature code written. You can test file_split.php easy enough by

I've been doing a lot of work with the MailChimp API V. 3.0 over the past year while developing the Cultivate CRM WordPress Plugin and I created the following helper function that has made live a lot easier for me since I have to make probably a dozen calls to the API within this one plugin.

I've been doing a lot of work with the MailChimp API lately and figured it would be good to have a page dedicated to it here for future reference because it's not very well documented online anywhere else... Hoping this will help some people who also have to use MailChimp's API.

Understanding MailChimp Lists and the API

If you've ever dealt with MailChimp, you know that it is based on lists which can be segmented, grouped and managed all from the API as needed. Next I will demonstrate how to get a list of MailChimp lists and information on each list that exists.

Getting MailChimp List Information from API

Here's the code I created to get all MailChimp Lists and information on each list from the MailChimp API using PHP code:

What is WooCommerce API Manger?

WooCommerce API Manger is used to secure your software with API License Key activation, deactivation and automatic updates of WordPress plugins and/or themes. However it can also be used for some applications outside of WordPress as well, but we will be talking mostly about how to use it with a custom WordPress plugin.

Prerequisites

You need to at least make sure you have at least PHP Version 7.00. Here's how you can check from the linux command line:

php -v

Type the above command and press enter and you should get results that look similar to this:

Alternative Solution to WooCommerce API Manager

You may have noticed this article isn't complete. That is because I decided to go with a different system for selling WordPress plugins on my site with API keys, WooCommerce didn't provide the level of support I needed and their documentation was poor. I discovered Easy Digital Downloads which was much simpler to deploy. Easy Digital Downloads(EDD) in combination with the EDD Software Licensing add-on and the EDD Instant Updater for plugins that I developed myself, became the ultimate solution for selling WordPress plugins outside of WordPress.org. If anyone is interested in how I did it, email me at linian11@yahoo.com and I can assist you.

In this PHP tutorial, I'll be showing you how to send text messages to cell phones from a website or app using PHP with a simple HTML form to collect the data. The only drawback to sending messages from PHP is that you typically need to know the receiving party's cell phone carrier in addition to their phone number. The only existing method of getting around having to know the person's cell phone carrier is to use a paid service to send SMS messages such as an SMSC or Short Message Service Center. One provider of SMS services is https://www.twilio.com/.

What are your SMS messaging needs?

This is an important question you should answer before proceeding because if you need to be able to send text messages with just a phone number and the message content, then you'll need an SMSC like Twilio, otherwise, if you don't mind making the user enter their Cell Phone Carrier name in addition to their phone number in a form to send a text message to them, then the free solution I'm about to show you will work fine for you.

Sending Text Messages From PHP

The basic high level steps to building an application to send out text messages from a web form are as follows:

Built an HTML form that submits to a PHP processing script and that collects the receiving party's phone number, cell carrier name and the text message content.

Create the PHP processing script to receive and process the information gathered in the form and send out the text message, using an email service, to the receiving party.

The entire process in it's simplest form is outlined below:

Write the HTML form. I created a folder named "SMS" and put a new PHP file named "index.php" inside the folder, then added the HTML for the text messaging form as you see here:

...the above code goes right after the </form> tag from above, then save the file as sms.php and upload it to your server and try to send yourself a message. If you use a different carrier than the ones provided in the code, you may need to add some options. A complete list of carriers can be downloaded online from https://davidwalsh.name/demo/SMS-Carriers.pdf

Here is a ready to copy and paste version you can simply copy all the below code into a file and save it as a .php file and it should work out of the box for the carriers listed in the provided dropdown:

<!DOCTYPE html>
<html>
<head>
<title>SMS via PHP</title>
</head>
<body>
<h1>Send Text Messages Online for Free!</h1>
<p>Yes, you can send SMS or Text messages online for free using PHP and sendmail. You simply have to provide all of the information requested in the below form and click the send text button to deliver it to the phone number you entered. You must know the receiving party's phone carrier for this to work however.</p><p>Tip: you can usually get the carrier of someone's phone by looking at an email they have sent you and reading the part after the @ symbol in the "From" email in the header of the email you received.</p>

Taking it further

The main drawback to this method is that you have to also know the cell phone carrier, but I've thought of a way to overcome that with a bit of extra coding. I found this site that takes the phone number in three parameters so for my business line,(234) 650-2011, it would be like this:

http://fonefinder.net/findome.php?npa=234&nxx=650&thoublock=2011

I plan to write a PHP script to resolve the address and scrape the results to get the carrier name. It will be a little complicated because you'll need to get the carrier name and then translate it into the actual email for ea. carrier, but it is definitely possible with some work.

Summary:

That's all there is to it! You can definitely improve upon this version of course as it is just meant to get you started. There is no form authentication and only very limited cell phone carriers listed in the dropdown, but the resource is provided to add more carriers from https://davidwalsh.name/demo/SMS-Carriers.pdf, so feel free to build onto what I've started here and let us know what improvements you've made in a comment so others can learn from it!

Here are the two commands you can run from the Mysqli Command Prompt to successfully clone a database table. In the example we will name our tables new_table_name and old_table_name where old_table_name is the table we wish to clone. This is the best way I have found to-date to create a backup of a mysqli table from the command line:

3) Once you have the saturation vapor pressure and actual vapor pressure, relative humidity(RH) can be computed by dividing the actual vapor pressure by the saturation vapor pressure and then multiplying by 100 to convert the quantity to a percent:
RH =(E/Es)*100
RH =(2.1211957981192776150462474985589/6.6907349413770067935260257174923)*100
RH = 0.31703479762758596814611114744566 * 100
RH = 31.703479762758596814611114744566%
SO... Humidity is 31.7%

And note here that ** means to the power of. I figured I'de clue anyone in that is as ignorant is I was when I had to figure it out.

PayPal has worked for me for several years and, while they have been mostly good to me, when you do need help, their customer service is practically non-existent. I had a horrible experience with them recently that has made me decide not to use them any longer for a while. I'm almost exclusively a seller and almost never a buyer which makes PayPal a poor choice for me it seems now. I have never had a dispute in all the years I've used PayPal until recently and I can not forgive the way PayPal handled that dispute. If you want to hear my story, read on, if you want to get right to using Payoneer as I suggest if you are a seller of goods or services like me, use this link to sign up for Payoneer now:

My Experience with PayPal

My bad experience that makes me want to completely stop using PayPal has to do with a former client of mine that filed a dispute after I had to inform them that I had to quit working for them because another client needed me(the other client that needed me has been a client for many years and the client I quit working for was new). When I quit working for the new client, he still owed me roughly $200 in my opinion. He had paid me a deposit of $200 when I started working with him because I always get a deposit to protect me from newer clients. I had completed a total of $400 worth of work before I quit working for him however, so really he still owed me $200. I was going to forgive the money he owed me however, since I had quit because I figured he wouldn't pay it anyway. So, for being a nice guy, the new client rewards me by filing a dispute on PayPal asking me to return $95 to him! I was shocked, but had confidence that PayPal would see it for what it was, an attempt by a client to get his money back even though I had completd the work, Fraud. So I refused to return the money and he escalated his false claim. To my surprise, without doing any investigation what-so-ever, PayPal made a decision in his favor. Okay, so I lost, I could have handled that without closing my account, but the kicker is that they didn't just reward the client the $95 he was asking for, they reversed the entire $200 payment he ad sent me! After losing the dispute, I first tried to call PayPal's "customer support" and was told I would have to wait on hold for over an hour! I waited on hold regardless of the ridiculous amount of hold time, but the call was never answered so I gave up after over an hour of waiting for a human to speak with about my issue. Then I sent them sent an email asking them why and got a computer reply that had absolutely nothing to do with the questions I asked in the email. So obviously, I was getting nowhere and it is clear now that I just got ripped off for $200 by PayPal and my former client. So, hello Payoneer! I'll let you all know how this new payment method works for me. Hopefully better than my experience with PayPal! Again, here's the link for Payoneer if anyone else wants to check them out:

My experience with Payoneer

So, while I am new to Payoneer, I will post my experiences here so others can benefit from them. First off, if you want or need to get your money immediately(Like you could with a PayPal Credit card if you were lucky enough to be approved), then Payoneer might not be the best service for you. I sent out my first invoice several days ago, on a Thursday to a client I completely trust and that client informed me that he paid the invoice immediately that same day, so the invoice was paid on Thursday. It is now the following Saturday and the invoice is yet to be even marked as paid in my Payoneer account. That kind of worries me. I read in their F.A.Q. that it can take from 3-5 business days, so luck me, it's the weekend! Right? Oh well, so that means it has only been one business day so far and the fifth business day would be next Thursday. I have to say that it it in fact takes that long, I won't be happy with the services at all. On the other hand, it the payment is in my account by Monday or Tuesday, I will be satisfied, not perfectly happy, but barely satisfied. I currently hate PayPal so much that I don't mind waiting a few days to get paid another way. However, a week is too long, so I'll let you all know asap when I can actually get the funds that were sent to me last Thursday. FYI, here's an image from Payoneer's website regarding information about the billing service I used to send my first invoice to my long-time trusted client:

A lot of times I am required to rename large quantities of files according to various rules. Sometimes this task can take hours to complete. Today I had a job requiring me to rename all files in a program that contained "xi" with "nap". The program had thousands of files in a dozen different directories. It would have taken days for me to go through them all manually and replace ea. occurrence of "xi" in the file names with "nap", so I tested several tools to help me do the job. The most capable tool I found was named simply "ReNamer" and can be downloaded from:
https://www.den4b.com/products/renamer

I downloaded the "portable" version of ReNamer version 6.7 Here is a screenshot of ReNamer's simply UI:

How to Download and Open ReNamer for First Use

First things first, so here is how to get started:

Use the link https://www.den4b.com/products/renamer to download the portable version of ReNamer and it will download a zip file to your PC. Place the file on your desktop and right click it and select "Extract All". Windows will extract the files and probably open the folder for you. Then click on renamer.exe to start the app. You will see the UI as in the above image. I like using this portable version because it is very light-weight and can be used on any PC. When I'm done using it, I simply delete the entire unzipped folder but I save the .zip folder I downloaded so I can use it again when needed and it doesn't waste any space on my PC when it's not in use. Next time I need it, I simply extract the files again and use it. Then I delete the folder when done again.

Find and Replace Text in File Names of Many Files at Once

It is easy as pie to use too! It only took me a couple of test runs to achieve the renaming rules I needed to do the job at hand. Just click where it says "Click here to add a rule" and add a rule. I needed to find and replace text in the file names, so in my case, I clicked on "replace" in the left panel so the add rule screen looks like this:

All I had to do was simply enter "xi" in the "find" field and "nap" in the "replace" field and click the "Add Rule" button to save your new rule. Then all you have to do is drag the folder containing all the files you want to rename into the UI as in the first image above, where it says "Drag Your Files Here". Then it gives you a preview of what files it will rename. Once you are happy with how it's doing the renaming, click the "Rename" button in the upper right corner of the UI and it will rename all of the files just like it showed you. If you have tested any of the other features of this tool, please comment below and describe your experience!

Today I set up a new server and I am documenting exactly how to set up multiple domain names, sub domains and websites on a new Apache2 Server. I am using Ubuntu, but I believe these directions are similar for any Linux Apache2 web server.

Pointing your domain or sub-domain

It is a good practice to point your domain name or sub-domain first, before you set it up on your server which I'll cover afterwards below, so let's go ahead and point our domain. Whether you are using a new domain name or a sub-domain on one of your existing domain names, the process is similar for pointing the domain name or sub domain name to your server IP address. You will need to go to your domain management console and create a Type "A" record. This will normally be done in your DNS provider's advanced DNS settings or zone file settings. Use the following settings to create two new records:

Name: if there is a name field, enter the domain name or sub-domain name(most require you to follow the domain with a "." so for my sub domain I entered "subdom.jafty.com.".

Type: "A" for both records.

Hostname field: enter "www" in the first record and "@" in the second.

Destination IPv4 address(sometimes just called Address): Use your server's IP address for both records.

TTL: use "14400" for both records.

That should be enough information for you to figure out how to create your two host records on just about any platform, but if your platform differs, ask your provider for assistance or google the providers name followed by DNS instructions or "How to point a name with Provider Name". You are creating two similar records, one for WWW and one for @. That way visitors of your site can access with either www.example.com or just example.com. The Hostname of @ makes the record for the domain without "www" in front of it. If your provider's DNS settings do not include the Host or Hostname field where we put either www or @, then you probably need to create two records with different names instead. For example, name one record "example.com." and name the other "www.example.com.". If you're using a sub domain then name one "sub.example.com." and the other "www.sub.example.com." You don't really need a www record for sub domains usually, but you can use one if you want, it won't hurt anything and might help some users find your site.

Steps to adding a second domain name to your server

Here I am going to explain how I set up a sub domain as as second domain name pointing to a second website on my Linux/Apache2 web server:

Note: My first site was already set up in var/www/html. Most people prefer to set up multiple websites under the var/www directory, but to keep things simple, I'm going to use the var/www/html folder and not var/www. It really makes no difference. It's just a preference.

Create your directory structure for your new website that will reside on your new domain or sub-domain. I'm creating a sub domain like subdir.jafty.com, but these directions are the same as if I were using just jafty.com instead. First, create the directory /var/www/html/subdir.jafty.com. Then create /var/www/html/subdir.jafty.com/logs and /var/www/html/subdir.jafty.com/public_html. If you are logged into FileZilla as root, you can create these from there, otherwise log in with putty and create them using the sudo command.

Create your log files. Simple make two empty files named access.log and error.log and upload them to the logs folder you created in step one above.

Create a VHOSTS file named after the domain or sub-domain followed by .conf, so in my case, I'd name my file subdir.jafty.com.conf. THen copy and paste the content below under the heading "VHOSTS Example File Contents" into it then change all instances of my sub-domain name with your own domain or sub domain and upload that file to /etc/apache2/sites-available.

Next, use the a2ensite tool from the Linux command line to finalize the new site with the following command(replace example.com with your domain or sub-domain): sudo a2ensite example.com.conf

Automating the process of setting up domain names and sub domains

If you have to do this often or alter DNS records often and create lots of virtual hosts, you should probably look into automating the process. I provide such a service and have done so for several of my clients. What I do is create a simple user interface in a secure admin web page on your own server where you can simply enter the domain name or sub domain name into a form field and press GO and it does all the above work for you! A real time saver if you have to do this more than once in a great while! IF you are interested in this service, contact me, Ian L. of Jafty.com for a fast, free quote by email or Skype. My email is linian11@yahoo.com and my Skype name is ianlin11. Or use the contact link on this site.
